System and method to synchronize signals in individual integrated circuit components

摘要

A synchronous output signal generated by an integrated circuit (IC) component is synchronized to an applied clock signal for each individual IC component. A variable feedback delay in the IC component is incrementally altered to alter the phase skew between the clock signal and the output signal. The relative phase order of the clock and output signals is monitored in the IC component. In response to detecting a swap in the relative phase order of the clock and output signals, the variable feedback delay ceases to be altered. In some embodiments, the IC component may be a SDRAM component.
